実験手順

To a slurry of 3.3 g (9.2 mmol) N-(4-fluorobenzyl)-2-(hydroxymethyl)-3,4-dimethyl-7-oxo-4,7-dihydrothieno[3,2-b]pyridine-6-carboxamide in 200 mL anhydrous DMF at 0° C., was added 3.0 mL (22.7 mmol) 2,4,6-collidine and 0.75 g (6.14 mmol) 4-(dimethylamino) pyridine. To this mixture, 1.8 mL (23.3 mmol) of methanesulfonyl chloride was added in two portions of 0.9 mL. The mixture was allowed to slowly warm to room temperature with stirring over night. After 19 hours, the homogeneous dark brown mixture was poured into 1.0 L of water. The resulting slurry was stirred for 2 hours at room temperature. The solids were then collected by vacuum filtration, washed with additional water, and dried in a vacuum oven at 60° C. over a weekend. This provided 2.91 g of the title compound as a tan solid.
